There are currently some ontologies of business collaboration that facilitate automated collaboration, such as evalue, REA, and BMO. However, these ontologies model the situation that all business actors can be trusted. This is not true in practice. To realize automated business collaboration, trust needs to be added to the business ontology. In this paper, we extend the evalue ontology with th...

In this paper, we question the nature and dimensions of eValues. We apply our approach to electronic marketplaces (EMPs), as an illustration of interorganizational information systems. The research is based upon 50 interviews made in 6 EMPs, and a thematic analysis on the themes linked to “the value of EMPs”. Our results categorise the different perceptions of eValues according to the different...

The article focuses on the integrated environmental accounting model called ‘eValue’, developed for protected areas and applied in research programme coordinated by Italian Ministry of Environment aimed at implementing an system Marine Protected Areas (MPAs). eValue adopts a cost-benefit analysis approach.

In this paper we show how business value modelling and enterprise architecture can blend into an integral approach for modelling e-services business cases. The approach, building upon evalue and ArchiMate, allows to link revenues and cost in a single model. The approach is illustrated on by the business case model of a virtual laboratory in the process industry. First experiences have shown sig...

The VALUE-IT project is addressing the problem of developing techniques to allow adaptive service configuration using evalue support. Such a service configuration also must match with specific consumer needs. In this sense, the first step is to deal with the problem of designing techniques to perform automatic service configuration. Consequently tasks related with IT elicitation, reuse of knowl...

Chemical extractants used to measure labile soil metal must ideally select for and solubilise the labile fraction, with minimal solubilisation of non-labile metal. We assessed four extractants (0.43 M HNO3, 0.43 M CH3COOH, 0.05 M Na2H2EDTA and 1 M CaCl2) against these requirements. For soils contaminated by contrasting sources, we compared isotopically exchangeable Ni, Cu, Zn, Cd and Pb (EValue...

Business value and coordination process perspectives need to be taken into consideration while modeling business collaborations. The need for these two models stems from the importance of separating the how from the what concerns. A business value model shows what is offered by whom to whom while a coordination process model shows how these offerings are fulfilled operationally. This case study...
